Embodiment Construction
[0032] The present invention will be further described below in conjunction with accompanying drawing:
[0033] Such as figure 1 As shown in , it is a structural schematic diagram of a prefabricated concrete floor structure.
[0034] A prefabricated concrete floor structure of the present invention comprises a panel 1, the panel 1 includes an outer finish layer 11 and a bottom layer 12, and an insulation layer 2 and a concrete layer 3 are sequentially arranged between the outer finish layer 11 and the bottom layer 12; The thermal insulation layer 2 and the outer finish layer 11 are set in the structure to meet the requirements for thermal insulation and inner wall surfaces in areas such as workshops.
[0035] Such as figure 2 As shown, a keel 4 is arranged in the concrete layer 3, and the keel 4 includes a number of longitudinal support keels 41 parallel to each other. The longitudinal support keels 41 mainly play a load-bearing role; The keel 431 and the lateral positioni...

The invention discloses a prefabricated concrete floor structure and a construction method thereof. The prefabricated concrete floor structure comprises a panel, the panel comprises an outer finish coat and a bottom layer, and an insulation layer and a concrete layer are arranged in sequence between the outer finish coat and the bottom layer; and the concrete layer is internally provided with a keel, the keel comprises a plurality of longitudinal supporting keels which are in parallel, the longitudinal supporting keels are connected though transverse keels, first connecting sleeves and secondconnecting sleeves are arranged at the two ends of the transverse keels separately, the first connecting sleeves and the longitudinal supporting keels are matched in a clearance mode, the second connecting sleeves are closely matched with the longitudinal supporting keels, and the first connecting sleeves and the second connecting sleeves on the same longitudinal supporting keel abut against eachother. The construction method includes the steps of assembling and connecting the keels, installing positioning pieces, pouring and connecting floors. The prefabricated concrete floor structure can solve the problem of insufficient anti-seismic property of concrete floors for a factory building in the prior art, and is low in cost, high in efficiency and wide in application range.
Description
technical field [0001] The invention relates to the technical field of building construction, in particular to an assembled concrete floor structure and a construction method thereof. Background technique [0002] The floor slab is a kind of separated load-bearing member, and its materials are generally brick arch floor slabs, reinforced concrete floor slabs and steel lining boards. Among them, high-altitude buildings or large-span factory buildings that need to bear force and ensure strength generally use reinforced concrete floors to ensure their structural strength. [0003] The floor layout of existing concrete single-storey industrial buildings generally still follows the rules formulated in the last century. In its design, earthquake resistance issues are less considered, and problems such as cracking after small earthquakes are very likely to occur, which brings great safety hazards. Contents of the invention [0004] The present invention aims at the above-mention...
